Do you have any questions?

Air flow measurements in ducts, temperature measurements in laboratories, humidity measurements in production, pressure difference measurements in clean rooms. The testo 480 digital temperature, humidity and air flow meter comes with a wide range of optional sensors that allow you to measure, analyse and log these and a variety of other parameters with only one device.

The testo 435-4 multifunction indoor air quality meter allows you to carry out all the measurements you need to inspect and adjust ventilation and air conditioning systems and to check the quality of the indoor air. There is also an integrated pressure difference sensor for pitot static tube measurements and filter monitoring and a wide range of optionally available sensors and probes to choose from.

You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.

Multi-function climate measuring instrument: measure up to 6 measurement parameters at the same time

testo 435 is a series of multi-function climate measuring instruments made by Testo. The testo 435-1 version is the entry-level measuring instrument in this series. You can use this to carry out measurements which you need to adjust ventilation and air conditioning systems and assess air quality. For this we offer you a comprehensive range of optional probes and sensors to choose from.

You have the option of connecting thermal anemometers and vane anemometers for measuring air velocity and volumetric flow in ventilation ducts

Air quality: measurement of CO2, air humidity, air temperature and absolute pressure with the optional IAQ probe

Make sure you get the testo 420 volume flow hood for larger ceiling outlets and at the same time enjoy multiple maintenance benefits on HVAC systems. Because the flow hood with the removable measuring instrument is not only exceptionally light, it also guarantees accurate volume flow calculations at swirl outlets

testo 435-3 – multi-function climate measuring instrument with integrated differential pressure measurement. You can use this to carry out measurements which you need to adjust ventilation and air conditioning systems and assess room air quality. For this we offer a comprehensive range of optional probes and sensors to choose from.

Includes differential pressure measurement for filter monitoring or for measurement with a Pitot tube

Further optional probes can be attached: thermal and vane anemometers, along with probes for air humidity, CO2, absolute pressure and temperature
